摘要:
A programmer allows a clinician to identify desirable combinations of electrodes from within an electrode set implanted in a patient that enable delivery of desirable neurostimulation therapy by an implantable medical device. The clinician may create neurostimulation therapy programs that include identified desirable electrode combinations. In some embodiments, the clinician may use the programmer to select a program, such as a program identified during a neurostimulation programming session, and direct the programmer to replicate the selected program. The programmer may change one or more parameters of the selected program, such as pulse amplitude or duty cycle, when generating the copy of the selected program. In some embodiments, the programmer may associate each of a plurality of programs identified during a neurostimulation therapy programming session with one or more program categories, and may automatically generate program groups that include two or more of the programs based on the program categories.

Techniques for performing lead functionality tests, e.g., lead impedance tests, for implantable electrical leads are described. In some of the described embodiments, an implantable medical device determines whether a patient is in a target activity state, e.g., an activity state in which lead impedance testing will be unobtrusive, such as when a patient is asleep, or capture information of particular interest, such as when the patient is active, in a particular posture, or changing postures. The implantable medical device performs the lead functionality test based on this determination. Additionally, in some embodiments, the implantable medical device may group a plurality of measurements for a single lead functionality test into a plurality of sessions, and perform the measurement sessions interleaved with delivery of therapeutic stimulation.

A programmer allows a clinician to identify combinations of electrodes from within an electrode set implanted in a patient that enable delivery of desirable neurostimulation therapy by an implantable medical device. The programmer executes an electrode combination search algorithm to select combinations of electrodes to test in a non-random order. According to algorithms consistent with the invention, the programmer may first identify a position of a first cathode for subsequent combinations, and then select electrodes from the set to test with the first cathode as anodes or additional cathodes based on the proximity of the electrodes to the first cathode. The programmer may store information for each combination tested, and the information may facilitate the identification of desirable electrode combinations by the clinician. The clinician may create neurostimulation therapy programs that include identified desirable program combinations.
摘要:
In general, the invention is directed to techniques for shifting between two electrode combinations. An amplitude of a first electrode combination is incrementally decreased while an amplitude of a second, or subsequent, electrode combination is concurrently incrementally increased. The stimulation pulses of the first and second electrode combinations are delivered to the patient interleaved in time. In this manner, the invention provides for a smooth, gradual shift from a first electrode combination to a second electrode combination, thereby allowing the patient to maintain a continual perception of stimulation. The shifting techniques described herein may be used during programming to shift between different electrode combinations to find the most efficacious electrode combination. Additionally, the techniques may be used for shifting between different electrode combinations associated with different stimulation programs or program sets.

The disclosure is directed to techniques for shifting between two electrode combinations. An amplitude of a first electrode combination is incrementally decreased while an amplitude of a second, or subsequent, electrode combination is concurrently incrementally increased. Alternatively, an amplitude of the first electrode combination is maintained at a target amplitude level while the amplitude of the second electrode combination is incrementally increased. The stimulation pulses of the electrode combinations are delivered to the patient interleaved in time. In this manner, the invention provides for a smooth, gradual shift from a first electrode combination to a second electrode combination, allowing the patient to maintain a continual perception of stimulation. The shifting techniques described herein may be used during programming to shift between different electrode combinations to find an efficacious electrode combination. Additionally, the techniques may be used for shifting between different electrode combinations associated with different stimulation programs or program sets.
摘要:
The disclosure is directed to techniques for delivering electrical stimulation for patient notification. An implantable medical device (IMD) may deliver patient notification stimulation via one or more device site electrodes, e.g., electrodes located proximate to an implant site for the IMD, configured as cathodes. Anodes for delivery the patient notification stimulation may be located in an electrode array that is provided by one or more leads and located distally from the implant site, e.g., an electrode array located at one or more target sites for delivery of stimulation therapy. In some embodiments, the IMD may inhibit the patient notification stimulation for a period in response to input from the patient, and then resume the stimulation at the end of the period. In this manner, the notification stimulation may be “snoozed” like an alarm clock. When the stimulation resumes, it may be different, e.g., more urgent, then prior to inhibition.
摘要:
A medical system and method of establishing communication between a plurality of implantable medical devices and an external device. An identification command is sent transcutaneously to at least one of the plurality of implantable medical devices. The plurality of implantable medical devices respond to the identification command with an uplink response in one of a plurality of uplink time slots. The external device receives the uplink response from each of at least one of the plurality of implanted medical devices. The external device establishes transcutaneous communication to a selected one of the plurality of implanted medical devices based, at least in part, upon an order in time of which the plurality of implanted medical devices respond with the uplink response.
